Convert sk1 to ico

What is the difference between .sk1 and .ico?

Description: An SK1 vector graphic file is a file format primarily used by the sK1 illustration program, which focuses on providing professional-quality design features for prepress processing. Unlike other vector formats, the SK1 file format is unique for its support of CMYK color, which is crucial for color accuracy in printing. It also includes advanced features such as color profiles and spot colors, making it particularly suitable for tasks that require precise color matching and high-quality print outputs.; An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
